Notes about this visit to Senator McNary's farm are on page 26 of a 1974 interview by Elwood R. Maunder (ERM) with F.Paul Keen (FPK) www.foresthistory.org/Research/Keen_Ohi_Final.pdf
"ERM: Did you ever have any personal contacts with Senator
McNary? Could you characterize his interest and his personality?
FPK: Yes. Senator McNary's personal interest was due to his having a farm near Salem, Oregon. Something was killing the tops of the white firs on his farm, and we were asked to make an appraisal. We soon found out that Chermes [balsam woolly adelgid] was doing the damage. Of course, the Bureau did not have any money for control so we took no action. We got in wrong with him for not doing control and putting his personal trees under protection. He was a little bit crabby the next time we went down there because we had failed to help him out.
ERM: Didn't you explain to him that you didn't have financial resources to do that?
FPK: That didn't cut any ice with him. He said he had done all these things for the Bureau. He thought the least we could do would be to come down and take care of a situation like that."
